Hello,I often charge my iphone or ipod from the cigar lighter using a cigar to usb plug converter. It works very well, but it has a small light on it which never goes out. The cigar sockets on my Focus 2009 are live even with the ignition off. So I am trying to find an adaptor which does not have a light which will waste my battery power.

I know I could take it out every time, but you forget, and also it is tight and hard to pull out.
